Maaloula had been overrun by rebel forces including members of the al-Qaeda-linked al-Nusra Front, at the weekend.

Some Syrian media reported that the government forces had recaptured the town.

But our Middle East editor says the fighting is ongoing, with al-Nusra still present in parts of the town. He says smoke is rising from some districts and he has seen injured government soldiers being evacuated.

More than 100,000 people have died since the uprising against President Bashar al-Assad began in 2011.

Meanwhile, the latest report by UN rights experts, released on Wednesday, says torture and rape are widespread and war crimes are being committed by both sides.

'Encouraging signs'

Russia announced its plan on Monday and Syria quickly responded, saying it "welcomed" the initiative.

Late on Tuesday, Foreign Minister Walid Muallem then made the fullest public admission of the regime's stockpile and a much clearer commitment to the Russian plan.

Analysis

Jim MuirBBC News, Beirut

Even without President Obama's uphill struggle to win over the US Congress and people, there's a strong feeling in the region that the psychological moment was lost in the few days after Parliament took Britain out of the picture on 29 August. The head of steam that seemed to herald an imminent attack has dissipated, and it is hard to imagine it being recreated.

"If they had hit then, when the moment was hot, they might have got away with it in terms of repercussions," said one diplomat. "But to come back cold, weeks later, would be something else."

Syrian rebels had been poised to exploit an American blow by trying to advance. Now they've suffered the double disappointment of seeing Mr Obama mired in domestic woes and then seizing the lifeline thrown by the Russian initiative, dismissed by the opposition coalition as a trick to win time.

Mr Obama has also made it clear throughout that he was not pushing for regime change, more cold water for rebel hopes. The chemical weapons crisis has not stopped the conflict grinding on in almost all parts of the country, with about 100 people killed daily and no end in sight.

"We are ready to inform about the location of chemical weapons, halt the production of chemical weapons, and show these objects to representatives of Russia, other states and the United Nations," he said.

"Our adherence to the Russian initiative has a goal of halting the possession of all chemical weapons."

But the BBC's Daniel Sandford in Moscow says there still appears to be disagreement between the Russians and the Syrians over whether the weapons should be destroyed.

He says the Syrians are eventually likely to concede the point and allow the arsenal to be destroyed because the Russians will argue that is the only way to gain broader acceptance of the plan.

Until Tuesday morning, Mr Obama's government had been lobbying hard for support in Congress for military strikes.

But surveys of politicians had shown he was unlikely to win the planned vote.

"It's too early to tell whether [the Russian plan] will succeed, and any agreement must verify that the Assad regime keeps its commitments," he said.

"But this initiative has the potential to remove the threat of chemical weapons without the use of force, particularly because Russia is one of Assad's strongest allies."

Americans in Washington react to the speech

He said the diplomatic movements were in part a result of the credible threat of US military action, but that he was willing to hold off pushing for a congressional vote in order to allow diplomacy to be pursued.

He added: "Meanwhile, I've ordered our military to maintain their current posture, to keep the pressure on Assad and to be in a position to respond if diplomacy fails."

What the US media say

President Obama appealed for support for military action "both from conservatives - who generally oppose his policies and are weary after backing the war in Iraq - and progressives - who largely put him in office due to his opposition to the invasion of Iraq", says the Huffington Post

The diplomatic option was the safest one for Mr Obama, says NBC, because he had appeared "to be on the cusp of losing a vote in Congress"

For Fox News, the real plaudits should go elsewhere: "In one of the most deft diplomatic manoeuvres of all time, Russia's President Putin has saved the world from near-certain disaster. He did so without the egoistical but incompetent American president, or his earnest but clueless secretary of state, even realising they had been offered a way out of the mess they'd created"

During his speech, Mr Obama restated the US position that Mr Assad's government was responsible for the 21 August attack, which he described as "sickening".

He said that such an attack was not only a violation of international law - it was also a danger to US national security.

He confirmed earlier reports that US Secretary of State John Kerry would meet his Russian counterpart Sergei Lavrov in Geneva on Thursday, adding: "I will continue my own discussions with President Putin."

France, which is the only other country to commit publicly to intervene militarily, said its forces would also remain "mobilised".

There were heated debates at the UN on Tuesday, with the UK, US and France calling for a timetable and the consequences of a Syrian failure to comply with any resolution spelt out.

Washington said it would "not fall for stalling tactics" and France warned against falling into a "trap" that would scupper any meaningful action against Syria.

The French put forward a draft resolution that would be enforced by Chapter VII of the UN charter, which would in effect sanction the use of force if Syria failed in its obligations.

"Hunting down banned chemical weapons in a secretive Middle Eastern dictatorship is not easy," as Frank Gardner reports

The draft resolution, obtained by Reuters, sets a 15-day deadline for Syria to provide a full account of the types and location of its chemical weapons.

It also says that if the steps leading to the transfer of control and destruction of the weapons are not met, "further necessary measures under Chapter VII" would follow.

Correspondents say Moscow opposes any resolution that would be authorised under Chapter VII, and that talks have foundered on the issue.

Russia has also said any draft resolution putting the blame on the Syrian government would be unacceptable, and urged a non-binding declaration backing its initiative.

I think the US France & the UK should table their resolution quickly so it can be voted ASAP. If Russia vetoes it then this would indicate that the diplomatic route had failed and US Congress should then vote on whether to carry out the military strike as put forward by President Obama. Any delay in taking action only strengthens Assad resolve to attack his own people.

Common sense at last, why not give this plan a chance? Destroy the chemical arsenal and let the Syrians get on with their own internal problems

We shouldn't be involved in this - there are too many factions and unseen interests stirring the pot here. Let the Arab/Muslim world sort out their own issues and let us sort ours out without interference

Obama has been outmanoeuvered on Syria. However, the UN and Russia in particular should look closely at their roles. The UN has proved once again it is nothing more than a pointless talk shop full of vested interests and they, along with Russia, haven't done enough to manage a negotiated agreement in Syria
